It's quite interesting to go back to the early development of chess playing programs. I remember, back in 1992 when I bought my first 286 PC and then got my Chessmaster 2100. I played the program regularly, and well, beat its strongest championship setting, it did print certificate for my winning too. Nowdays it's a dream to even draw with the latest Chessmaster if your are not a master. Just for curiousity I searched if the old program are still out there and the result is...YES somebody got the link for it, check it out below:

Amazingly the program runs on my Windows Vista using DosBox, still like it much although the graphic is not that fantastic!! No installation is needed, just create a folder, copy the files and run it from there. DosBox link is here: [DosBox Link]
Note that if you are not familiar with the old DOS commands, it would take a while for you to figure out how the DosBox works for you.
